Subject: [PATCH] mtd: spi-nor: enable stateless 4b op codes for mx25u25635f
|
|
|
|
All required stateless 4-byte op codes are supported by this flash
|
|
chip. The stateless 4-byte support can't be autodetected due to a
|
|
missing 4-byte Address Instruction Table in SFDP.
|
|
|
|
Fixes hangs on reboot for SoCs expecting the flash chip in 3byte mode.
